BENCH-VISE.

SPECIFICATION forming part of Letters Patent No. 742,096, dated October20, 1903. Application filed January 9,1903. Serial n3. 138.405. (Nomodel.)

To all whom it may concern:

Be it known that I, JOHN R. LONG, a citizen of the United States,residing at Akron, in the county of Summit and State of Ohio, haveinvented certain new and useful Improvements in Bench-Vises; and I dodeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art towhich itappertains to make and use the same.

My invention has reference to a bench-vise; and the object of theinvention is to provide a vise in which the adjusting-screw isconstructed to operate substantially within the limits of the fixed jawmember, and the several parts are adapted to operate substantially asshown and described, and particularly pointed out in theclaims.

Referring to the accompanying drawings, Figure 1 is a side elevationofthe vise complete and in readiness for use. Fig. 2 is a longitudinalsectional elevation thereof with the parts as in Fig. 1. Fig. 3 is across-section on a line corresponding to wrc,.Fig. 1. Fig. 4 is alongitudinal sectional elevation of the movable jaw member and thesleeve-nut therein. Fig. 5 is a plain elevation of the screw. v I

As shown, A represents the base of the vise, which is adapted tto besecured to any suitable support and is formed with an annular seat forthe body of thevise. The said body consists of two members or halves Band B, provided each with a section or half of a socalled trunnion orhub seatedin base A, and the said sections are adapted to be slightlytilted in respect to each other and their'seat, so that when they aredrawn toward each other at their top they will be pressed outward below,and thus lock frictionally in the said seat. This likewise is shown inthe foregoing application.

O and Dare the respective jaw members, and O is referred to as a fixedmember, because it remains stationary when the movable member Disadjusted to open orclose the vise. However, this so-called fixed memberis adapted to be rotated about its axis within the body of the vise, andit'is shown in this instance as having two diameters, the largerdiameter working in section B of the body and the sin allerdiameter issection B,and

a securing and bearing cap E isaffixed to the outer extremity of jawmember 0 by means of screws 2. This cap bears against the outer edge ofbody member B, and serves as a support and bearing for screw sleeve ornut'H.

G is the screw, and H the threaded sleevenut'therefor. This nut orsleeve has a head 3, which bears against the outside of cap E andextends thence through the same into screw G between its head 7 andfixed collar L thereon. Sleeve J is loose as to the screw to affordfreedom of turning; but it is designed to be driven or forced tightlyupon its seat in member D, so as to serve as a reliable backing forcollar L when the screw is rotated to open jaw D. This also gives head 7of the screw a solid bearing against the full stock of jaw D, and thereis nothing to break or give way or become weakened under severe strainor pressure through the action of the screw. By this construction also Ican run screw G entirely out of the sleeve-nut H after having firstremoved cap 9 from its end, and then by a little extra exertion I canpull the screw bodily out of memberD and bring sleeve J with it. Thisalso liberates sleeve ornut H, which can be withdrawn in the oppositedirection. Said nut should be secured by some means against rotationwhen the screw is turned, and I find that a close fit in cap E providesfrictional engagement about its outside which is sufficient therefor;but it can have some special fastening, if desired.

By making the inner portion of the hub of jaw member 0 heavier than theouter portion I get greater strength where itis needed, and it willbeunderstood that when the screw is tightened it tilts the body sectionstoward each other and locks them against rotation in base A.

It will be seen that the collar L and sleeve J occupy an annular recessin jaw member D about screw G, while head 7 of the screw bears againstsaid member just outside said sleeve.

The inner jaw member has a splined connection with the outer member, soas to prevent its rotation in respect thereto.

What I claim is 1. The combination of the base, the body consisting oftwo separate members supported in the base and adapted to be tiltedtoward each other and thereby lock in the base, the jaw members, a capresting against the outer portion of the said body and screws supportingthe cap on the outer jaw member, a sleevenut supported by said cap andprojecting into the inner of said jaw members, and a locking screw forthe jaw engaging said nut, substantially as set forth.

2. The base, and the body consisting of two independent tilting membersrotatable and adapted to be frictionally locked therein, in combinationwith the jaw members rotatable together in said body, a cap mechanicallyconnected with the outer of said jaw members and bearing against saidbody, a sleevenut having a head engaged against said cap and projectinginto the bore of the inner of said jaw members, and a tightening-screwfor the jaw members engaged with said nut, substantially as set forth.

3. In bench-Vises, a body for the vise consisting of two separate partsanda base in which said parts are seated and adapted to be rotated, saidparts constructed to frictionally lock against rotation when tilted insaid base, a pair of jaw members one within the other and rotatabletogether in said body, and means to confine and operate said jawscomprising a cap removably fixed to the outer extremity of the outerjawmember and bearing against the outer part of the said body, a sleeve-nuthaving a head engaged with said cap and extending into the inner jawmember, and an operating-screw engaged within said sleeve, whereby whenthe said screw is tightened it looks the body of the vise and the jawmembers against rotation, and means on the outer end of saidoperating-screw to prevent the same from being run out of the saidsleeve-nut when the vise is opened, substantially as described.

l/Vitness my hand to the foregoing spocifi' cation this 22d day ofDecember, 1902.

JOHN R. LONG.
